CALCULATING MACHINE Filed Dec. 1, 1933 2 Sheets-Sheet 2 INVENTOR Emesf Facz BY ATTORNIEYS Patented Oct. 13, 1936 UNITED STATES PATENT OFFICE CALCULATING MACHINE Ernest Baez, Detroit, Mich, assilnor to Barroughs Adding Machine Company, Detroit, Mich a corporation of Michigan This invention relates to a calculating machine and is directed particularly to a construction for selectively numbering all or certain transactions entered in the machine.

It is an object of this invention to provide an improved selectively operable numbering device for a calculating machine whereby items entered into the machine may be designated by some printed number.

It is a further object of this invention to provide a selectively operable numbering device controlled by one or more control keys.

It is still another object of this invention to provide a selectively operable numbering device which may be controlled by a key to number items entered into the machine in a consecutive or repetitious manner.

In manylines of business it is desirable not only to list and add the various transactions entered into a machine but also to number the items or transactions for the purpose of counting or of indicating certain transactions by numbers,

. so that the transactions can later be readily identitled to permit the user of the calculating machine to compute the average value of a certain group or of the entire number of transactions. For example, it is frequently desirable to post invoice numbers consecutively and also to repeat the same number on the invoice in other instances.

posit slips, it is required to perform consecutive numbering of some items while repeat numbering other items. In bill receipting it is desired to print consecutive numbers on the bodies of successive bills while repeating the bill number on the stub of each bill. Other instances of desired selective consecutive or repeat numbering will be manifest to those familiar with bookkeeping. It is therefore advantageous to provide a numbermachine showing the numbering mechanism controls set to cause a numbering operation to take 55 place but before the machine has operated.

In another instance, such as posting bank detioned Horton patent.

Calculating machine in general I The invention is illustrated as applied to a 1 Burroughs" portable calculating machine of the type shown in the Horton patent, 1,853,050, to which reference may be had for details of the calculating mechanism. It will be manifest that the invention can also be applied to calculating machines of other types.

Briefly, the calculating machine comprises a plurality of banks of amount keys i0 (Fig. 1) which control the differential movements of stop bars I I connected to actuator racks li'with which two registers I3 and H are associated. The actuator racks also index and operate a printing mechanism including type bars i8 (Fig. 2) and type hammers ll. The machine is also provided with a bank of control keys A, B, C, D, and E, for conditioning the machine and causing the numbering mechanism to perform in selected or desired manner.

The machine may be operated by means of either an electric motor (not shown) or a hand crank 18 (Fig. 1) through a dlsconnectible drive in the manner illustrated in the heretofore men- The driving motor or crank oscillates the main drive shaft l9 (Fig. l) the two movements in the oscillation being known as the forward and return stroke.

As described in detail in the Horton patent, each rack I2 is raised to a differential position upon operation of the motor or hand crank as determined by the depression of its amount key and the corresponding type bar It is raised to its indexed position. Continued operation of the machine causes the hammer latches to be released to permit the hammers l'l to fire and strike the type bars it to cause an imprint to be made upon the paper 20 traveling over a platen 2|. At the same time, of course, the items are being accumulated in either of the registers II or it which were previously selected by means common to these types of machines.

Numbering mechanism or disk type and comprises a plurality of disks 22 (Fig. 4 having type 23, positioned to print upon the paper 20 on platen 2|. The disks are accessible to the operator for presetting or resetting as desired Disks 22 are pivoted on a shaft 24 carried by a frame 25 pivoted to the machine side frame at 26 (Fig. 3) and normally urged clockwise thereabout by a spring 21 until an upward extension 28 of frame 25 rests against a hammer 29 for actuatingthe numbering type 23.

Hammer 29 is pivoted on a stud 36 (Fig. 3) and is constantly urged counterclockwise thereabout by spring 30 and contains a rearwardly and downwardly extending arm 3i engageable under certain conditions with a latch 32 carried by shaft 33. Shaft 33 is carried by yoke 34 pivoted at 35 to the machine frame. Yoke 34 is oscillated at each operation of the machine by the main shaft l9 and is given a counterclockwise movement during the forward stroke of the machine, and returned in a clockwise direction upon the return stroke of the machine. Shaft 33 is the hammer latch supporting shaft for operating hammers i1, asshown in the heretofore mentioned Horton patent for which reason it is not described with greater detail herein. Yoke 34 contains a forwardly extending forked arm 36 shown in full lines in Fig. 3 and in dotted .lines in Fig. 1 which engages a stud 31. carried by crank 38 pivoted at 39. Crank 38 is provided with a downwardly extending arm 40 to which is connected one end of a link 4| (Fig. 1) the other end of which is connected to'the main drivregular printed item.

That is, at each operation of the machine the main" shaft I9 is rocked first clockwise and then returned counterclockwise to normal position.

During this movement crank 38 is rocked in the same relative direction causing stud 31 to oscillate yoke 34.

Accordingly, when yoke 34 is rockedcounterclockwise during the forward stroke of the machine, latch 32 is moved into position until it engages arm 3| of hammer 29 moving the ham-' mer from the position shown in Figs. 1 and 2 to.

the position shown in Fig. 3. When hammer 29 is rocked forwardly, an upwardly projecting arm 43 (Fig. 3) thereof engages a pin 44 projecting inwardly from the frame 25 and positively moves the latter forwardly in addition to the force of spring 21.

Control of numbering mechanism The present invention provides controls where- I 34 continues its counterclockwise movement slightly, arm 46 pivots the latch 32 clockwise 'tively during operation of the machine.

(Fig. 3) until it releasesits hold on arm 3| of After, a number has'bee'n printedon the paper by the type carried by the numbering dials, spring 2'! restores the numbering device and frame clockwise so that the numbering dials engage hammer 29 at a position a slight distance away from the platen and ribbon to permit movement of thelatter.

Selective control of operation of numbering dials To allow for a slight movement of the num-.- bering frame relatively to hammer 29- to permit printing, a slight clearance is necessary and is provided between -pin 44 and arm43 of hammer 29 when the hammer 29 is in uncooked or normal position. This slight-clearance enables the numbering dials to engage the platen and print upon the paper thereon under momentum of the frame after movement of the hammers has been blocked. The numbering mechanism is placed under control of one or more of the operation control'keys so that the numbering mechanism is operable only upon certain designated operations of-the machine as Will nowbe' explained.

Referring particularly to Fig. 2, it will be seen that the operation control key E when depressed engages and rocks a crank 56 in a counterclockwise direction which through link 5! rocks a three-arm lever 52 in a counterclockwise direction. Lever 52'is provided with a forwardly extending .arm carrying'a stud 53 which engages the lug 54 of the lever 55 pivoted at 56.. Ac-

. cordingly, when control key E is depressed the lever 55 is rocked in a counterclockwise direction. Lever 55 extends tb-the rear of pivot 56 and contains a forked arm 51 which engages a stud 58 carriedby an arm 59 fixed to a cross shaft 60 extending to the left side of the machine; The extreme left end of shaft 66 supports the downwardly extending arm 6! shown in dotted lines in Fig. 2 and more clearly'in Fig. 3 which arm engages a stud 62 under said conditions carriecl by the latchmember '32.

In normal condition, that is, if no operation key is depressed, lever B! engages stud 62 and retains latch 32 in a clockwise and inoperable position where it does not engage hammer 29, as shown in Fig. 1. Consequently, if the machine is given a stroke of operation without depressing control key E, or A, as will later be explained, latch 32 is in inoperative position, that is. it will not engage hammer 29 during a machine operation and accordingly moves. ineffec- Depression of control key E, however, will cause arm 6| (Fig. 3) to move in a counterclockwise direction and permits latch; 32 to move into position to engage hammer 29 upon operation of the machine causing an actuation of the numbering device upon operation of the machine.

Consecutive numbering A means is also provided for controlling the advancing of the numbering dials so that the number printed thereby can be advanced during successive operations or so that the same $21M! can be printed as often as may be de- The three arm lever 52 is provided with a rearwardly extending arm having a stud and forked connection I! with a yoke member 88 which latter member extends from the right to the left side of the machine where a forwardly extending arm 61 is secured thereto (Figs. 1 and 3). Arm 61 is provided witha stud and fork connection 68 (Fig. 3) with a vertical slide I! having pin and slot connection ID with a stationary frame of the machine. The upper end of slide 69 is provided with a cam face which under certain conditions engages a stud 12 carried by a yoke 13 journaled on shaft 24 (Figs. 3 and 4).

Yoke ll carries a spring operated member H having fingers 15 thereon which are adaptable to the numbering disks 22 to advance the latter in consecutive manner, common to counting wheels in series.

When the operation key E is depressed (Fig. 2) and the yoke 68 rocked as above described, slide 89 (Fig. 3) is raised from the Fig. 1 position to the Fig. 3 position in which position slide 69 limits the forward movement of stud 12 when the hammer 29 and frame 25 are moved in a clockwise direction causing yoke 13 to move in a clockwise direction on shaft 24. Clockwise movement of yoke ll causes finger 15 to engage the numeral disks 22 to advance the numeral disks one unit in value, during the forward motion of the numbering device and before the printin has actually taken place. Accordingly, the advancing of the numeral dials and the printing is all controlled and takes place during a single operation of the numbering mechanism caused by depression of key E.

Repeat numbering Provision is also made for causing the numbering mechanism to print repeatedly the same number upon successive operations of the machine.

Referring more particularly to Fig. 2 it will be seen that depression of operation key A instead of operation key E causes the lever 55 to rock counterclockwise independently of the three arm lever 52, thus when the key A is depressed its engagement with the three arm lever 55 rocks the operation control keys so as to be selectively operable to perform a numbering operation when desired although it is normally inoperative. It is also possible selectively to, perform consecutive numbering and/or repeat numbering as desired. Itwill be apparent, of course, that additional keys other than operation control keys A and E may be provided with suitable connections to the numbering mechanism and that instead of employing a multiple numeral disk counter, a single disk with a suillcient number of numeral type thereon may be employed.

The flexibility is increased by having a separate control key for controlling the advancing of the numeral wheels for consecutive numbering and an independent control key for controlling the operation or nonoperation of the numbering mechanism. The advancement of the numbering mechanism for operation during the forward stroke of the machine, i. e., during the same operation on which the numeral or numbering device is printed, rather than on the preceding machine operation makes it unnecessary to determine until the last moment whether the numberingisto take place or whether the numbering is to be consecutive or repeat.

Other additional advantages and novel features will be apparent to those skilled in the art from the foregoing description. ,It will also be apparent that minor changes may be made in the description' without departing from the spirit and scope of the claim.

I claim:

A calculating machine having calculating means controlled by a plurality of amount determining and total taking keys, means for giving said machine cycles of operation, a numbering mechanism capable of printing upon each cycle of machine operation, means for advancing said numbering mechanism upon a cycle of machine operation, a pair of control keys in addition to and independent of said amount and total keys, means common to said control keys and operatively associated therewith for conditioning said numbering mechanism to print upon a cycle of machine operation, connections between one of said keys and the said common enabling means for actuating the latter to condition said numbering mechanism to print the same values upon succeeding cycles of operation, connections between the other of said control keys and said common enabling means for actuating the latter, and further connections between said other control key and said advancing means to condition the latter to advance the numbering mechanism during each cycle of machine operation whereby consecutive numbers are printed under control of said other key when the machine is cycled.
